According to that experience, it doesn't look like an easy or straightforward job to fit 275/30 tires (RE-11s in that case) on stock front wheels without using spacers (he recommends 5mm.), or maybe without a camber mod instead of/in addition to spacers. Both PSS and RE-11 seem to be larger than usual tires, to be kept in mind!

There are a few people who did 295/30 on stock rear wheels, some reported minor rubbing mostly on certain bumps, loaded car/compression situations and some said zero issues. None that I remember was with a lowered suspension though. Most were with PSS tires.

So, other than not being super ideal size (but doable) for our stock wheels, those tire sizes are as close to stock diameter and stagger as it gets and there are plenty of M3 guys who has nothing but good things to say about that particular combo, with PSS.

I will definitely try some set up other than the stock (basically for scientific curiosity purposes, not because I had problems with stock size) when my current tires get cooked, this might well be that alternative. Won't happen very soon though.

I decided to not go so extreme for my DD's - 265/30 front and 275/35 rear, would have went 285 rear but TireRack didn't have them in stock for another weak and I'm down in the states on vacation right now and its allot cheaper to get them here and have them mounted before going back up North.
Just have to find a place in Chatham, Cape Cod to get them mounted LOL
